This product is perfect for those with a few grey strands, if you're over 10-15% grey you're probably going to want a more permanent solution.
I found it easy to apply, and really unnoticable once dry - its not like the horror of spray-on hair for bald men! It'd be perfect for evenings out, and weekends away as its small enough to fit in your bag.
I would definitely recommend it to those with a small amount of greys - if you have a lot of greys this would be great in a cover-up emergency, but wouldn't be a great long-term solution.
This simple hair mascara solves the grey strand problem! I stopped colouring my hair years ago, and I love my natural shade, but the grey coming through is a bit annoying.
I found this very easy to use, I just applied it over my greys, It covered them immediately. It didn't come off until I shampooed, and even then I didn't notice any pigment in the shower.
Recommend to those with grey strands they'd rather not see!
